Definitions

  • the present invention can be included in the technical field of vertical drawers used in maritime works. More specifically, it is a prefabricated drawer with fiber reinforced polymeric material that is mounted dry in port.
  • the levees are a structure used to reflect and dissipate the energy of the water from the waves and therefore prevent or reduce the action of the waves of an area to be protected.
  • Conventional levees adopt two basic typologies that constitute the slope levees and the vertical levees.
  • the levees are structures that are built in the sea to provide shelter to a certain area. These dikes are constituted by natural and / or artificial jets of different sizes and usually by concrete shoulders.
  • Vertical dikes are vertical, monolithic and waterproof wall structures. These dikes are constructed with reinforced concrete drawers and have a gravitational behavior, that is, the stability of the drawer is based on its own weight.
  • the fundamental characteristic of vertical dikes is that they reflect practically the total energy of the waves, returning the action of the waves as a rigid monolithic vertical wall.
  • the most common solution for the construction of vertical dikes is the use of prefabricated reinforced concrete drawers, which are manufactured in the sea and floated to their final position where they are anchored. The use of drawers in these constructions also allows the formation of dikes and docks for the berthing of ships and the containment of landfills to obtain surface platforms.
  • the drawers that are known in the state of the art have cells inside, which are generally rectangular cells or circular cells.
  • the drawers are generally built in floating installations that can be floating docks, submersible pontoons guided from fixed structures or catamarans with submersible platform.
  • the usual process of construction of the drawers consists in concreting the floor to later concreting the shaft with sliding formwork. As the drawer is concreted, it draws into the water. Later it is transported to its final position by a tugboat that pulls in the bow. A complementary stern tug can also be used to do the helm. When the drawer has been arranged on its final location, it is anchored to fix it in its final position.
  • the present invention proposes a drawer for maritime works, which can be used in all types of works but which is specially oriented to be used in vertical dikes.
  • the drawer for maritime work consists of a modular construction comprising, as a base, a floor that can be circular or polygonal.
  • the solera consists of a plurality of segments intended to be collaterally linked to each other by joining means. These segments include an internal sector, lateral sectors and an external sector that incorporates some coupling elements. The segments that make up the hearth are the same as each other.
  • the segments When it is a polygonal hearth the segments have a triangular or truncated triangle configuration. When it is a circular hearth the segments have a radial segment configuration.
  • the drawer comprises a series of segments designed to be placed collaterally with each other throughout the perimeter and on the floor to form a closed surface.
  • the segments have an upper side, lateral sides and a lower side.
  • the lateral sides have means of lace between segments, to allow the coupling between them.
  • the lower side is intended to fit the coupling elements of the segments.
  • the surface that is generated with the collateral junction of the segments in a preferred embodiment is cylindrical.
  • An essential characteristic of the proposed drawer is that the pieces that make it up, that is to say the segments and the segments, are made of polymeric materials reinforced with fiber. Said parts are manufactured at the factory and are subsequently transported to the place of assembly of the drawer, which is preferably a port near its final position. In this way, when the drawer assembly is complete, it is simply thrown into the sea from the dock and towed to its final position where it is anchored.
  • the assembly of the pieces that make up the drawer is done dry and the different joining means used to fix the pieces together can be mechanical joining means, such as tongue and groove between the pieces or rivets. They can be chemical bonding means, such as an adhesive resistant to seawater or a laminate with the fiber itself and resin of the drawer but executed in situ and that gives continuity to the piece. Also the joining means can be a combination of mechanical means and chemical joining means.
  • the segments can have a single wall or be double wall. The choice of one type of dovela or another will depend, for example, on the strength required in each application, on manufacturing conditions, overall dimensions of the drawer, etc.
  • the segments have a simple wall, they can comprise vertical stiffeners that provide greater structural resistance to the drawer.
  • the segments are double-walled, they comprise an outer wall and an inner wall, joined together at least by the lateral sides of the segment, and may be open on the upper side and the lower side.
  • the gap between the outer wall and the inner wall can be used to introduce a ballast material for the towing stage of the drawer, for anchoring or it can be filled to achieve greater strength of the drawer.
  • the segments can also comprise a receptacle inside which the lower side of the segments can be inserted.
  • the hearth additionally comprises a central body, also of fiber reinforced polymer, to which the inner sectors of the segments are linked by corresponding joining means.
  • the central body can be cylindrical or prismatic.
  • a procedure for assembling the drawer for maritime work described above. Said process comprises the steps of joining the segments collaterally with one another by means of joining and joining the segments collaterally with each other, by means of fitting means between segments, fitting the bottom side of the segments into the coupling elements of the segments.
  • the method comprises introducing stiffeners inside the main space which is the space that is created inside the surface of revolution generated by the segments.
  • the segments and the segments are transported to a spring in which the assembly is carried out.
  • the pieces are transported to the dock where the dry assembly is carried out.
  • the commissioning includes the stages of throwing the drawer into the sea, ballasting the drawer by partially filling the main space, towing the drawer by sea to its final position and anchor the drawer by filling in the main space.
  • the assembly of the pieces is done in dry work with the help of a crane. This lowers costs because specialized labor is not necessary for work on the high seas or underwater. Furthermore, the assembly operations are greatly simplified and the complete assembly can be carried out in a short time.
